Overheating on other Grand Cherokee years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016, 2017, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
Most owners in this group notice the coolant before they notice the heat: a reservoir that keeps dropping, a sweet smell, or a bright puddle under the front of the car. Across the vehicles on this site, about four in five of these complaints mention coolant, a leak or a puddle, and roughly two in five mention the temperature gauge or overheating.
What got replaced
Owners who name the part that was replaced mention the coolant hose or reservoir (15 reports), the radiator (9 reports) and the thermostat (4 reports).
Recalls and investigations
4 recalls on the engine cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.
The crankshaft position sensor tone wheel may delaminate, causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall.
The Exhaust Gas Recirculation (EGR) cooler may crack and allow pre-heated vaporized coolant to enter the EGR system. This mixture may combust inside the intake manifold.
The crankshaft position sensor tone wheel may delaminate causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall.
The supercharger mounting bracket may contact and damage the ABS line, possibly resulting in a brake fluid leak.

Is this a known problem?
The manufacturer has sent NHTSA 3 service bulletins or notices for the 2014 Jeep Grand Cherokee that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Water Quality When Mixed With Engine Coolant
Issue involves overheating, running hot, coolant leaks and related symptoms after a Mopar replacement engine has been installed in the vehicle.
Water Pump Dealers are replacing water pumps because of a coolant leak. Water pumps are found TNF but the water pump bypass o-ring was pinched resulting in a coolant leak that looks like a failed pump.
What owners wrote
“In 2022 our 2014 grand jeep cherokee Pentastar oil filter housing cracked leaking oil and mixing with the coolant.While driving both levels became dangerously low and there was a burning smell. It is now 2023 and our 2015 jeep wrangler just had the exact same issue with the Pentastar oil filter housing crack and oil leaking to dangerous levels. This is a known issue with Jeep, why are there no safety recalls ??”

“Power steering, engine acceleration, coolant/radiator, belts, eco diesel system, blind side detectors and automatic emergency breaking have all been major issues with this jeep. I've almost been crashed into by other vehicles, including an 18 wheeler, because of the engine instability. It is now in the repair shop and completely unable to drive.”

“Was pulling a trailer and vehicle overheated and caused radiator to leak. Dealer states exhaust fumes were present in coolant overflow tank and states engine needs to be replaced, but refuses to believe this is caused by an EGR Cooler that is under recall”

Should you keep driving it?
This page can't tell you that. 0 of 48 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
